263# <a href="http://quest.arc.nasa.gov/antarctica/QA/computers/Directions,Time,ZIP">
264# From Craig Mundell (1994-12-15)</a>:
265# Vostok, which is one of the Russian stations, is set on the same
266# time as Moscow, Russia.
267#
268# From Lee Hotz (2001-03-08):
269# I queried the folks at Columbia who spent the summer at Vostok and this is
270# what they had to say about time there:
271# ``in the US Camp (East Camp) we have been on New Zealand (McMurdo)
272# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
273# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
274# of GMT). This is a time zone I think two hours east of Moscow. The
275# natural time zone is in between the two: 8 hours ahead of GMT.''
276#
277# From Paul Eggert (2001-05-04):
278# This seems to be hopelessly confusing, so I asked Lee Hotz about it
279# in person.  He said that some Antartic locations set their local
280# time so that noon is the warmest part of the day, and that this
281# changes during the year and does not necessarily correspond to mean
282# solar noon.  So the Vostok time might have been whatever the clocks
283# happened to be during their visit.  So we still don't really know what time
284# it is at Vostok.  But we'll guess UTC+6.

350#
351# From Chris Carrier (1996-06-27):
352# Siple, the first commander of the South Pole station,
353# stated that he would have liked to have kept GMT at the station,
354# but that he found it more convenient to keep GMT+12
355# as supplies for the station were coming from McMurdo Sound,
356# which was on GMT+12 because New Zealand was on GMT+12 all year
357# at that time (1957).  (Source: Siple's book 90 degrees SOUTH.)

360# http://www.cybertours.com/whs/pole10.html
361# (1995-11-13 16:24:56 +1300, no longer available):
362# We use the same time as McMurdo does.
363# And they use the same time as Christchurch, NZ does....
364# One last quirk about South Pole time.
365# All the electric clocks are usually wrong.
366# Something about the generators running at 60.1hertz or something
367# makes all of the clocks run fast.  So every couple of days,
368# we have to go around and set them back 5 minutes or so.
369# Maybe if we let them run fast all of the time, we'd get to leave here sooner!!
